Abstract (en)
[origin: EP0405560A2] The present invention relates to a method for the preparation of tertiary-hydrocarbylsilyl compounds through a Grignard reaction. A Grignard reagent of formula RMgX, in which R is a tertiary-hydrocarbyl group and X is a halogen atom, is reacted with a silicon compound of formula R<1>aSiX4-a; where R<1> is a substituted or unsubstituted monovalent hydrocarbon group and a is an integer with a value of zero to three. The process is ran in the presence of a catalytic quantity of a cyano compound or a thiocyanate compound.
